Ambry Genetics

Apr 25, 2022

The c.839A>G (p.Y280C) alteration is located in exon 8 (coding exon 8) of the ARHGEF33 gene. This alteration results from a A to G substitution at nucleotide position 839, causing the tyrosine (Y) at amino acid position 280 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
